ENDOCARDITIS Viridans streptococci have a strong association with bacterial endocarditis (see site) (Box 1). A defectiva and A adjacens were once an important cause of culture-negative endocarditis. However, current laboratory media and techniques enable these “nutritionally variant streptococci” to be identified more readily. 2. BACTEREMIA Viridans streptococci account for 2.6% of positive blood cultures reported from clinical laboratories; however, of these, only about one-fifth are thought to be clinically significant (the remainder are attributed to contamination or transient bacteremia). Viridans streptococci are, however, one of the leading causes of …

Most enterococcal urinary tract infections are nosocomial and are associated with urinary catheterization or instrumentation. BACTEREMIA & ENDOCARDITIS Nosocomial enterococcal bacteremias are commonly polymicrobial. Portals of entry for enterococcal bacteremia include the urinary tract, intra-abdominal or pelvic sources, wounds (especially burns, decubitus ulcers, and diabetic foot infections), intravascular catheters, and the biliary tree. Metastatic infections other than endocarditis are …

The term “primary bacteremia” refers to positive blood cultures without an identifiable anatomic focus of infection. Differentiation of primary bacteremia from infective endocarditis (IE), in which infection of the cardiac valves leads to continuous bacterial seeding of the bloodstream, may challenge even the most experienced clinician. Primary S aureus bacteremia is associated with insulin-dependent diabetes, the presence of a vascular graft, and, most significantly, the presence of an indwelling intravascular catheter. Risk factors for IE include structurally …

Aminoglycosides High doses of parenteral penicillin can inactivate aminoglycosides. In patients receiving low doses of aminoglycosides because of reduced renal function this can be clinically important. Parenteral administration of these drugs in neonatal dosages does not seem to produce relevant inactivation, and so temporal separation of the infusions is not required. Piperacillin protected against aminoglycoside nephrotoxicity without reducing its blood concentration; this was possibly a protective effect of co-administered mineral salts. Ciclosporin …

Acute severe dyspnea with cyanosis has also been observed without symptoms of bronchial obstruction or pulmonary edema. Specific mechanisms for such cases have yet to be identified. Allergic pneumonitis and transient eosinophilic pulmonary infiltrate (Loeffler’s syndrome) are rare. These syndromes have also been observed with penicillin hypersensitivity. In one case, an alveolar allergic reaction, probably due to ampicillin, showed features of an adult respiratory distress syndrome. Nervous system High doses of penicillins, …

This is only likely to be a problem in patients with heart disease or in those who are receiving drugs that delay ventricular repolarization. High-doses intravenously have caused ventricular fibrillation and torsade de pointes. Each episode of dysrhythmia, QT interval prolongation, and myocardial dysfunction occurred 1-1.5 hours after erythromycin infusion and resolved after withdrawal.

Comparative studies The safety and efficacy of topical ofloxacin ear-drops 0.3% (0.25 ml bd) have been compared with that of co-amoxiclav oral suspension (40 mg/kg/day) for acute otitis media in 286 children aged 1-12 years with tympanostomy tubes in place. Topical ofloxacin was as effective as and better tolerated than systemic therapy with co-amoxiclav. Treatment-related adverse event rates were 31% for co-amoxiclav and 6% for ofloxacin.
